Thanks, Meera for initiating this.

I would like to join as well and perhaps share some efforts on making earth
observation training data open (work in progress) among others.

Re: [datameet] Re: Query about the 2011 Districts shapefile

[Ashim Kapoor]

Dear Devdatta,

OK. I wonder why I get 531/641 matches if the codes do not have the
SAME meaning in both (the map and the lgdirectory ) datasets.

What about ST_CEN_CD and DT_CEN_CD in the 2001 / 2011 Districts
shapefiles ? Are those BOTH  the Census codes for States and Districts
respectively in 2001 ?

I wish someone wrote a README explaining the column names in 2001/2011
Districts and States shapefiles.

Best,
Ashim

Re: [datameet] Re: Query about the 2011 Districts shapefile

[Devdatta Tengshe]

When this data was created, the Census Tables were not available, and it
was created by digitising the maps given in the Administrative Atlas PDF
available on the Census Website.

So it included only the numbers available in the Administrative Atlas, and
not the actual codes that are available in the CENSUS Tables.

Source: I was part of the India-WRIS team which had created this data.

Regards,
Devdatta

Re: [datameet] Re: Query about the 2011 Districts shapefile

[Ashim Kapoor]

Dear Devdatta,

Many thanks for your reply.

The website:

https://lgdirectory.gov.in

has Census 2001, Census 2011 codes for ALL Districts of India.

Example on this website:

For the State of Maharashtra, the districts Ahmednagar, Akola and
Amrawati have Census 2011 codes = 522,501,503.

In the 2011 shapefile the `censuscodes` for 522,501,503 correspond to
Districts Ahmadnagar, Akola Amrawati.

I have done a "outer join" of District names by
censuscode=Census2011.Code and I get 531 / 641 matches.

Please see the attached text file. I do not think this is happening by
"chance". I do think that the censuscodes column in the 2011 Districts
shapefile is the Census 2011 codes for Districts.

Best,
Ashim

Re: [datameet] Re: Query about the 2011 Districts shapefile

[Devdatta Tengshe]

The 'censuscode' is just a sequential ID, going from 0 (for POK Areas) to
640.

As far as I know, it has nothing to do with either the 2001 Census code or
2011 Census.

Devdatta
